ReceptionRating · Positive reviews · Number of ratings

Dr Evil's Math Challenge Game holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Celestwald adventure has 13 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 67% of Dr Evil's Math Challenge Game's written reviews are positive against 100% of Celestwald adventure's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Dr Evil's Math Challenge Game ships an update every 91 months, Celestwald adventure every 3 months. The most recent releases landed on October 28, 2026 and October 24, 2026 respectively.
